The veneers l/I) are usually gluedto the wrest-plank B, and the veneers b form a pin-b1ocl which is fittedto the frame A before the pin-block b is secured to the wrestplank B, sothat when the wrest plank is secured to the frame A, as by the screwsand bolt, as in Fig. 1, the pin block b is firmly clamped and held inthe recess in the frame A.
